'it I i Be itfknown that IVWILLIAM HENRY ELLAM, artist, of Keswickf Croydon' l Poad, Anerley, Surrey, England, 'have' inventedcertain new and useful Improved venting side slip or skdding.

In all constructions hitherto proposed where side slip is prevented .byl means of chains disposed upon the tread of the tire' -the said have been distributed over the tire' tread in'such manner that they had to take theweight` ofthe vehicle during ordinary running and consequently the chains were subject to .undue wearand the constant presence of the chains betweenthe tire and theroad tended to damage the j projections;y at the' sides of the tread as to a'llow the in tire toa serious extent.

'I By. the present'` invention we so'dispose the chain or equivalently a row of links, studs or other metallic termediate part of the tire or tread toA come into contact with the road in the usual manner, the sidey chains only into operation to prevent side slip.

y IThe'invfeuntion preferably takes the form of an outer cover or band and this band is or may 'be formed of a "number of sections lor segments detachably secured around the tire and closely. arranged so'asto abut at their ends). said sections or segmentsbeing provided with non-slipping devices in the form of' chains or studs, arranged lengthwise 'of the tread, or circumferentially of the tire', so that when the segments are assem-i bled upon`the tire an outer cover or'band is obtained l having circumferential rings or bands around the tread which afford an ecient safeguard. against side.

' slip and as the band is formed of segments, upon any part of the saine becoming damaged or worn, repairs can easily `be eHected by substituting a new segment for that lwhich is damaged, without disturbing the vention are illustrated in whichl Figure ll'is a part side elevation of a motor tire having the invention applied thereto. Fig. 2 is ai plan ofl Fig. 1, Fig. 3 is a cross section of Fig. 1, and Fig. 4 is an enlarged detail.

' Referring to the drawings, a a are segments of leather or other suitable material adapted wheny assembled upon the tire to form a continuous band or cover. The 'segments a a of the cover are preferably stamped or formed with extensions or tongues b provided with eyelets or slits c which engage upon the hooks or prov Specification of Letters Patent.

vcover upon theA tire. For the purposes of securing a firm attachment the pins are ttedl with hooked ends projecting towards the center of the wheel so that after the slits c are placed thereon the inflation of the tire will prevent the tongues becoming detached from the hooks. l

Along each side of the tread of the segments a of the outer'cover or band are disposed two parallel Irows of chains e of a corresponding length to that of the segments a and attached thereto by rivets inthe form of staples f adapted to embrace the chaine and b e riveted to the leather cover a as shown moi-e particularly in Fig. 4. The abutting ends of the chain sections aare connected together and thus a band in segments but v with continuousV circumferential rows of chain upon the tread is obtained. If required the length of chain in each section need notbe connected.

the side slip. Further by the use of a leather segmental cover, should any portion of the tread become damaged, the segment containing .suchdamaged part canbe readily replaced. The leather cover also protects the tire from the road and from any strains -put upon the tire by the chains or links. f

What I' claim and desire tosecure by Letters Patent 'IBI- ing circumferential rings of chain disposed along! the-side o f 'the tread thereof at such distance apart as will allow the segmental cover lto bear upon the road between thccliains, substantially as described.

2. The improved means-for preventing side slip in mo-o tor vehicles comprising a wheel tire, a cover ,to said tire, means for securing the said tire to the rim of the wheel, circumferential rows of chain fastened to said cover and disposed so as to louve in the center of the tire tread such a width of the cover surface exposedthut soidexposed surface will come in contact with thc rond during" normal running while the rows of chains at the side -svlll come into operation when side slip tends to occur.
